TECHNICAL FIELD

The present invention mainly relates to the field of medical device, and in particular, to a medical device provided with safety verification and a safety verification method thereof.

BACKGROUND

Diabetes is mainly a metabolic disease caused by abnormal human pancreatic function. Diabetes is a lifelong disease. At present, medical technology cannot cure diabetes. It can only control the occurrence and development of diabetes and its complications by stabilizing blood glucose. The normal human pancreas automatically monitors changes in the body's blood glucose levels and automatically secretes the required insulin. At present, the medical device for stabilizing blood glucose works by dynamically monitoring the blood glucose changes of the human body by a glucose sensor implanted in the subcutaneous tissue of the human body; and continuously accurately infusing insulin into the subcutaneous tissue of the human body through a medical cannula implanted in the subcutaneous tissue of the human body.

With the development of the Internet and software technology, patients can now remotely control drug infusions through software. However, remote devices connected to the Internet are vulnerable to interference, attacks, tampering, etc., posing great security risks. Prior art devices require safety verification before drug infusion. The device will only perform the drug infusion function if the safety verification matches the infusion instruction. However, in addition to infusion functions, non-infusion functions are also important, but the prior art does not provide safety guarantees for these non-infusion functions.

Therefore, there is an urgent need in the prior art for a medical device that requires safety verification for both infusion and non-infusion functions.

FIG. 1 is a schematic diagram of a workflow of a medical device executing a functional instruction according to an embodiment of the present invention, and FIG. 2 is a schematic diagram of a structure of each part of the medical device according to an embodiment of the present invention.

Step 1: The user operates the remote device 100 to send functional instruction(s).

In the embodiment of the present invention, information is exchanged between the remote device 100 and the functional device 110 through wireless communication. The user can control the functional device 110 to perform various functions through the remote device 100. The functional device 110 also feeds back the execution information or acquired information to the remote device 100.

The remote device 100 includes, but is not limited to, a mobile phone, a tablet computer, a smart watch (band), and a Personal Diabetes Manager (PDM). Specifically, in the embodiment of the present invention, the remote device 100 is a mobile phone. In another embodiment of the present invention, the remote device 100 is a PDM. In still another embodiment of the present invention, the remote device 100 is a smart watch.

The functional device 110 is used to perform functions directly related to medical purposes. In the embodiment of the present invention, the functional device 110 is adhered to the skin surface of the user through the adhesive tape 120. The functional device 110 can be a drug infusion device, a physiological condition detection device, or an integrated device for both detection and infusion. Specifically, in the embodiment of the present invention, the functional device 110 is a drug infusion device, and the functional device 110 injects the drug into the user through the infusion needle 121. In another embodiment of the present invention, the functional device 110 is an integrated device that combines detection and infusion. At this time, the structure 121 is provided with functions of both infusion and detection.

The drugs in the functional device 110 include insulin, glucagon, antibiotics, nutrient solutions, analgesics, morphine, anticoagulants, gene therapy drugs, cardiovascular drugs or chemotherapy drugs, which are not specifically limited here. Specifically, in the embodiment of the present invention, the drug in the functional device 110 is insulin. In other embodiments of the present invention, the functional device 110 may store a plurality of drugs described above.

The functional device 110 is capable of performing various functions, such as the basic drug infusion function. The user may send a drug infusion instruction to the functional device 110 through the remote device 100. Specifically, in one embodiment of the present invention, the drug infusion instructions include basal insulin infusion instructions and bolus insulin infusion instructions. For example, in an open-loop system or a semi-closed-loop system, the user operates the remote device 100 to issue basal insulin infusion instructions according to the amount of basal insulin required by the body at different time periods. Depending on the situation of food intake, the user can operate the remote device 100 to send bolus insulin infusion instructions.

In addition, the remote device 100, according to the embodiment of the present invention, can also send non-infusion instructions, so that the functional device 110 can realize other functions which will be described in detail below.

In actual operation, the user sends various functional instructions to the functional device 110 through the remote device 100. For example, when the functional device 110 is installed, the remote device 100 may send an instruction to activate or start the functional device 110. At the same time, the remote device 100 needs to be paired with the functional device 110, so they can interact with each other. In an embodiment of the present invention, when the functional device 110 is being activated, the remote device 100 can also send an instruction including remote device model information, so that the remote device 100 can pair with the functional device 110.

During use, the remote device 100 may send instructions to the functional device 110 to enable the functional device 110 to switch among different functions. For example, in one embodiment of the present invention, the functional device 110, as an open-loop system or a semi-closed-loop system or a closed-loop artificial pancreas, is a medical device for both detection and infusion and is used in the field of diabetes care. Receiving functional instructions from the remote device 100, the functional device 110 can be controlled to switch among these three systems.

The functional device 110 can also receive instructions for smart selection from the remote device 100. As in an embodiment of the present invention, the user sends an instruction through the remote device 100 to instruct the functional device 110 to intelligently select detection or infusion functions, or to intelligently select drug infusion amount, etc.

The functional device 110 also has a function of feeding back information to the remote device 100 as required. For example, the functional device 110 can feed back the detected physiological condition information, drug infusion data, or device condition information. The remote device 100 can therefore display the above information to the user according to the user's needs by communicating with the functional device 110.

During the use of the medical device, malfunctions may occur, such as suspension of drug infusion, loss of data, stop of detection, connection failure between the functional device 110 and other devices. The user may send a detection instruction for the above-mentioned faults to the functional device 110 through the remote device 100 to restore the medical device to normal operation.

In one embodiment of the present invention, the remote device 100 can be used as a supporting tool. When the medical device enters normal operation, the remote device 100 can send instructions to the functional device 110 to disconnect from the functional device 110. When necessary, the remote device 100 can send instructions to restore the connection with the functional device 110.

Step 2: The functional device 110 receives functional instructions.

At present, most of the remote devices 100 can be connected to the Internet, and the remote devices 100 and functional devices 110 are interconnected via Bluetooth. The remote device 100 and the functional device 110 are both exposed to risks of being hacked, tampered with, damaged, maliciously invaded, etc. There is also a risk that the remote device 100 is operated or misused by others, posing potential safety hazards, even life-threatening ones. For example, when the wireless communication is hacked, the drug infusion can be controlled by others, thereby endangering the user's health and life. Or when the remote device 100 is unintentionally touched by a child, the drug infusion amount may be increased or decreased, creating a safety hazard. As another example, when the communication between the remote device 100 and the functional device 110 is attacked, others can easily obtain the user's physiological condition information, resulting in data leakage. For another example, the device parameters and the communication between the devices may be easily tampered with or damaged, so that the device can no longer work normally, leading to potential safety risks and higher maintenance cost for the user. Therefore, in the embodiment of the present invention, after the functional device 110 receives the above-mentioned functional instruction, it needs to pass safety verification before the functional device 110 executes the corresponding function.

Step 3: The user sends verification instructions to the safety verification module in the functional device.

Specifically, in the embodiment of the present invention, the functional device 110 is provided with a safety verification module 111. After the safety verification module 111 receives verification instructions from the user, the functional device 110 starts to execute a corresponding function. Obviously, since there are many kinds of functional instructions, there also need to be many types of verification instructions to correspond to different functional instructions.

In the embodiment of the present invention, the safety verification module 111 includes a linear acceleration sensor or a gyroscope sensor. With a linear acceleration sensor or a gyroscope sensor as the safety verification module 111, the user only needs to perform simple body movements to complete the verification. In this way, the user does not need to carry other parts or devices, or may not even need to touch the functional device to complete the verification, which improves the convenience of the safety verification and enhances the user experience. Specifically, in the embodiment of the present invention, the linear acceleration sensor is a three-axis linear acceleration sensor. The three-axis linear acceleration sensor can detect acceleration changes in the three directions of X, Y, and Z axes. It has the advantage of enhanced sensitivity for motion detection and is capable of rapid detection of body movements. In another embodiment of the present invention, the safety verification module 111 is a gyroscope sensor. The gyroscope sensor can accurately detect the user's rotational body movements such as, torso twist, special way of walking and circling. In another embodiment of the present invention, the safety verification module 111 adopts a combination of a linear acceleration sensor and a gyroscope sensor, allowing the functional device 110 to detect the user's body movements more quickly and accurately.

In the embodiment of the present invention, the user's body movements include, but are not limited to, jumping, squatting, leg movements, arm movements, tap on the functional device 110, bending over, torso twist and special way of walking. It needs to be explained here that tapping on the functional device 110 includes not only direct contact with the functional device 110 but also indirect contact and non-contact. For example, the user can tap the clothing around the functional device 110. Leg movements include, but are not limited to, raising the leg and shaking the leg. Arm movements include, but are not limited to, vibrating arms and swinging arms. Special walking methods include, but are not limited to, forward and backward walking, circle walking and zigzag.

In the embodiment of the present invention, the verification instructions include single movement or a combination of multiple movements among the above-mentioned body movements, and no limit is set on the frequency of a certain body movement. Preferably, in the embodiment of the present invention, a certain verification instruction is to tap the functional device 110 three times. Tapping three times is chosen instead of one, two, or more than three times, which avoids the interference caused by accidental movements, and is more convenient and more user-friendly than tapping more than three times. In another embodiment of the present invention, the verification instruction for the basal insulin infusion is that the user bends down first, and then twists the torso twice. In still another embodiment of the present invention, the verification instruction for activating the functional device 110 is zigzagging.

As mentioned before, there are many kinds of functional instructions, so there should be also many kinds of verification instructions that match the functional instructions, and the body movements of some different verification instructions can be different or the same, but all different body movements are not exactly the same. Preferably, in the embodiment of the present invention, the verification instructions for starting and stopping the functional device 110 are the same, or the verification instructions for disconnecting and reconnecting are the same. Using the same movement for certain verification instructions can reduce the types of movements, which will reduce the manufacturing cost and improve user experience.

It should be noted that, in other embodiments of the present invention, more verification instructions may be allowed to use the same body movement, which is not specifically limited herein.

Step 4: The functional device executes the functional instructions.

After the safety verification module 111 receives the corresponding verification instruction, the functional device 110 starts executing the functional instruction. Obviously, in the embodiment of the present invention, if the verification instruction and the functional instruction do not match, the functional device 110 will not execute the instruction which improves the safety of the device.

In one safety verification method of a medical device, only the drug infusion instructions need verification, while other functions do not need to be verified, therefore the safety level of the medical device is relatively low. Moreover, it is necessary to use extra parts to perform verification via contact or electromagnetic induction, which requires complicated actions and generates poor user experience.

The safety verification method of the medical device according to the embodiment of the present invention can not only verify the drug infusion function but also other non-infusion functions with simpler method, higher safety level and better user's experience.

In summary, the present invention discloses a method for safety verification of a medical device. After a remote device issues a functional instruction for drug infusion or non-infusion functions, it is necessary to pass safety verifications before the functional device performs the corresponding functions, thereby improving medical device safety and enhancing user's experience.

Please continue to refer to FIG. 1 and FIG. 2 . Correspondingly, the present invention also provides a medical device for setting security verification, which includes a remote device 100 and a functional device 110. The functional device 110 is provided with a security verification module 111.
